Acroceridae
Sign in to saveAlso known as small-headed flies, hunch-back flies, spider flies
The Acroceridae are a small family of odd-looking flies. They have a hump-backed appearance with a strikingly small head, generally with a long proboscis for accessing nectar. They are rare and not widely known. The most frequently applied common names are small-headed flies or hunch-back flies. Many are bee or wasp mimics. Because they are parasitoids of spiders, they also are sometimes known as spider flies.

==Description== thumb|230px|left| Acroceridae plate from Johann Wilhelm Meigen|Johann Wilhelm Meigen's Europäischen Zweiflügeligen The Acroceridae vary in size from small to fairly large, about the size of large bees, with a wingspan over 25 mm in some species. As a rule, both sexes have tiny heads and a characteristic hump-backed appearance because of the large, rounded thorax.
